I have Vitocal 111-s 8kw heat pump and it starts on/off very often. My house is two flore and 150 square meters with heating flore and radiotors in second flore. When it is outside is around 6-10 it works around 15min and turns off then after 15min turns on and again work around 15min. In curve temperature is set about 29 when outside is +6 and it is good inside. What should I do about those turn on/off ?
